Some other Purāṇas discuss worship of materialistic gurus and relatives. They state, for example, that a wife should worship her husband even if he is not a devotee. But Śrīmad-Bhāgavatam never cheats us in any way. It directly states:
gurur na sa syāt sva-jano na sa syāt
pitā na sa syāj jananī na sā syāt
daivaṁ na tat syān na patiś ca sa syān
na mocayed yaḥ samupeta-mṛtyum
One who cannot deliver his dependents from the path of repeated birth and death should never become a spiritual master, a father, a husband, a mother, or a worshipable demigod.
What is the meaning of na sa syāt (one should not)? If a guru is not really a guru, if he cannot give love and affection for Kṛṣṇa, you should reject him. Such a guru may think, “All these disciples are my property, and I will enjoy their property. They have no connection with Kṛṣṇa. Their connection is only with me.” That guru is a wretched guru, not a real guru. He should at once be rejected, just as Bāli Mahārāja rejected his guru. There are so many examples of this in śāstra.
A husband is not a husband if he is not actually helping his wife in Kṛṣṇa consciousness; that wife should reject such a husband. If a wife is not helping her husband in Kṛṣṇa consciousness, or if a husband is not helping his wife in Kṛṣṇa consciousness, they should be at once rejected. If a son is not helping his father in Kṛṣṇa consciousness, then he is to be rejected as a son; there should be no relationship. If others help us in Kṛṣṇa consciousness, then they are guru, husband, wife, daughter, son, father, or friend. Otherwise you should reject* them. This must be the root of all relationships. If you consider some compromise in this regard, you will be deprived of Kṛṣṇa. This has all been clearly explained in Śrīmad-Bhāgavatam. The gopīs are the most superior devotees in the world, and all of them disregarded their husbands. Śrīmad-Bhāgavatam explains all these truths. It never says anything to cheat us.
*[Śrīla Bhaktivedānta Nārāyaṇa Gosvāmī Mahārāja has explained that ‘reject’ means to not give your heart to one who is not a devotee. It does not mean to abandon one’s duty to one’s family members. But if someone is actively opposing one’s endeavors in bhakti and obstructing one’s practices, that person can be rejected.]
